I think sometimes we forget thaf we're quite a new species and we're still (other than technology-wise due to our huge brains!) Developing to adapt to an ever changing society. We're also an amalgamation of various species of early man and we're now apparently all the same 'breed' but we're not. We're each made up of products of our parents grandparents great grandparents and our brains including coping mechanisms are hugely affected by what theirs were like.
Transgenerational trauma is also a significant thing. I agree with others regarding having childhoods that were traumatic-having ONE caring supportive adult who believes in you is huge. Even if it is a teacher you see once a week. It helps hugely compared to a child who has nobody on their side.
If we were able to delve deeply into the brains of our ancestors back 2000 years and understand what their development was like, I believe we'd have our answers but we can't thus far.
Trauma is a very funny thing indeed. TW violence.....
My ex assaulted me by strangulation and then picked me up and threw me backwards down a wooden staircase, some years back. Now, while that is not an experience I'd gladly repeat, aside from the physical injuries I am unscathed. I still see my ex and I am not afraid. I am not nervous around flights of stairs. I've never had a flashback of anything to do with it.
Fast forward to 2021 and my partner took me to a football match and treated me appallingly throughout. Ignored me. Bullied me to show off. 'Forgot'me and went to a different venue. Nothing major certainly nowhere near what my ex had done.
Up until recently I could not hear the sound of football on the TV without panic. I couldn't hear anyone talk about it..I even had a reaction while I was out walking the dog and there was a parked car with a football sticker in the back window. Had a couple of night terrors although I cannot be certain they're related, I had certainly never had one before.
Trauma is strange, very strange.⁹
